SPECIFICATION forming part of Letters Patent No. 286,811, dated October16, 1883,

Application filed February 21, 18831. (No model.)

T0 a/ZZ whom t may concern:

Be it known that I, FREEMAN HANsoN, a citizen of the United States,residing at Hollis,

in the county of York and State of Maine, have invented certain new anduseful Improvements in Turning-Machirfes5 and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification. V

Figure I is a perspective view from the front. Fig. 2 is a perspectiveview from the rear.

Fig. 3 is a top plan, Fig. 4, details showing how each cutter is madeand fixed in position on their shaft.

This invention relates to that class of devices designed for cutting orcarving wood or metal; and the novelty consists in the special detailsof the construction and the combination of the several parts, all aswill now be more fully set out and explained.

In the accompanying drawings, A denotes any suitable frame, in which theseveral parts Power is communicated in any desired manner, now indicatedas bymeans of p'ulley B, shaft b, and bevel-gear b b, which last mesheswith gear c on shaft C. On the outside, preferably, of frame A areplaced the train of gearwheels These gears are to be varied in size andnumber, as may be required to vary the speed of the shaft E, whichpasses through the upper gear, D'. This shaft is splined in gear D' andsupported in bearings c CLL-the latter movable horizontally on the trackF, in the upper and front part of the machine, by means of the screw G,

`which runs lengthwise just below the track F,

and passes through the lower end of a', and

has at its outer end a handle, g. This screw.

also works in like manner the moving bearing a2, which has in its upperend a screw, H. The wood to be turned is placed between the ends of theshaft E and screw H, the bearings a a? havingfbeen suitably set and thescrews G and H having been properly-adjusted, so as to X the wood rmlyin position, By this means the wood can also be readily moved back andforth, so as to offer it to one or another of the cutters I.` The trackF constitutes the upper part of the frame F', which swings on shaft C bymeans of the pitmanf, which has one end adjustably pivoted on the lugj"of the frame, and at the other is eccen trically connected to the end ofshaft b. Thus the frame F can be moved back and forth, as desired, bymerely setting the pitman f up or down in the lugj'". By this means thewood to be cut can be offered as may be desired to the cutters, toinsure such varied cutting as may be wanted.

The cutters I are spirally fixed on the shaft K, which` is supported inbearings Z on the swinging frame L, and are revolved by the pulley Z',over which aband from the driving shaft passes. The cutters have eacha'shank, i, which fits into a socket in the shaft K, and is therefastened by the set-screw z". Each cutter has an angled face, which isconcave on the under side, and by this peculiar shape, and by thepeculiar adjustment of the cutters on the shaftK and the movement of thewood to and fro and back and forth in front of the cutters, the mostdesirable results can be attained, as a very wide range of style ofcutting can be made. IVhile I have shown cutters of this peculiar shape,it is evident that I may use cutters of any shape. i

The frame L, which swings on the shaft G, canbe moved back and forth bythe handled screw M m, and thus the cutters can be moved to the work asmay be desired.

The cutters may be made in one piece with their shank, by which they areapplied to and fixed in the shaft; but the knife part mav be adj ustablyfixed to the shank, if desired, asis now illustrated in Fig. 3.

Having thus described my invention, whatI consider new, and desire tosecure by Letters Patent, is

l.` In awood-working machine, the movable and adjustable supports forthe wood, whereby both of the bearings which carry the parts that clampthe wood can be moved back and forth before the cutters, and likewiseclamping parts which can be so moved, all combined and operatingsubstantially as described.

2. The combination of the splined shaft E, passing centrally through andoperated by the gear-wheel D, the fixed bearing a, supporting saidshaft, the movable bearings a a?, for li0ldving the wood to be cut, thetrack F, and the screw G, by which said bearings are moved in saidtrack, substantially as described.

3. The combination of the bearings a a?, movable on the track F by meansof screw G, all as described, with tlie shaft K, provided with cutters Iand swinging on frame L, substantially as described.
